Abstract
Large-scale student assessments are a cornerstone of proposed educational reforms to improve student achievement from very low levels in low- and middle-income countries. Yet, this promise relies on their presumed reliability. I use direct audit evidence from a large Indian state (Andhra Pradesh) to show that, as currently administered, official learning assessments substantially overstate proficiency and understate the 'learning crisis' of low student achievement. In an experiment covering over 2,400 schools, I evaluate whether digital tablet-based testing could reduce distortion. Although paper-based assessments proctored by teachers severely exaggerate achievement, tablet-based assessments closely match independent test data and are much less likely to be flagged for cheating. Furthermore, I use the direct audit-based retest to directly validate existing (indirect) statistical procedures for detecting cheating at scale and establish that it would be feasible to monitor data integrity cheaply and at scale with such methods. Overall, these results suggest that well-designed technology-aided interventions may improve data integrity at scale, without which these learning assessments are unlikely to serve as a catalyst for policy action.

The South Asian civilization or the Indus Valley civilization, as it is more commonly known, is as old as antiquity itself. The permanent character of settlements is one of the defining features of this civilization. The maritime trade during the Indus Valley civilization was developed and it was well connected to Egypt, Mesopotamia (present day Iraq) and China. The Indus Valley сivilization was the first foray of the South Asian region into the international maritime trade and cultural diffusion with other parts of the world having a civilization. The amount of cultural, economic and social exchange and interaction can be ascertained from the archeological finds and it shows the intermingling and cross cultural influence among the then known and developed world.

We study the impact of a personalized technology-aided after-school instruction program in middle-school grades in urban India using a lottery that provided winners with free access to the program. Lottery winners scored 0.37 σ higher in math and 0.23 σ higher in Hindi over just a 4.5-month period. IV estimates suggest that attending the program for 90 days would increase math and Hindi test scores by 0.6 σ and 0.39 σ respectively. We find similar absolute test score gains for all students, but much greater relative gains for academically-weaker students. Our results suggest that well-designed, technology-aided instruction programs can sharply improve productivity in delivering education. (JEL I21, I26, I28, J24, O15)
